I just hopped on when I bought them and started spinning away. I've ridden off the edge a few times....but you just stop and put your foot down.

Even though I had zero trouble with starting rollers, I still can't really do it with no hands. I can ride on the road just fine with no hands, but the bike my rollers are set for has pretty steep angles and is very jumpy when it comes to cornering...

super cool. Scary how well it works on overprocessed pop crap like call me maybe...but it actually works pretty well for other songs too. Transitions are sometimes noticable, but it is damn good for being done by a program.
